Modern industrial production cannot do without the safe and stable service of pipeline systems. American Standard Seamless Pipe, with their excellent performance, are widely used and occupy an extremely important position in the field of industrial pipelines.
Shanghai Zhucheng Pipe Fittings Manufacturing Co., Ltd., as an excellent supplier of American Standard seamless pipe in the industry, is committed to providing high-quality products and comprehensive services to new and old customers at home and abroad.
Seamless steel pipe is a pipe with a hollow cross-section and no welds around it. It can be made of materials such as carbon steel, alloy steel and stainless steel, and processed through a series of complex processes such as perforation, hot rolling, or cold rolling. Due to the absence of welds, it exhibits excellent strength, pressure resistance, and sealing performance.
Its manufacturing standards are mainly produced by the American Society of Mechanical Engineers (ASME) and the American Society for Testing and Materials (ASTM), with sizes ranging from 1/8"to 48"and lengths in units of 6 meters and 12 meters. These standards have strict regulations on the size, material, performance, and other aspects of steel pipes to ensure that products can meet the high standard requirements of many industries such as petroleum, natural gas, chemical, power, and machinery manufacturing.
ASME B36.10M and ASME B36.19M are important standards for the size of seamless pipes in the American standard. Among them, ASME B36.10M specifies the dimensions of welded and seamless rolled steel pipes, which are applicable to materials such as carbon steel and alloy steel; ASME B36.19M specifically standardizes the dimensions of stainless steel pipes, and together they form a seamless pipe size specification system.
In terms of material standards, the ASTM series standards play a key role. For example, ASTM A106 specifies the manufacturing requirements for seamless carbon steel pipes in high-temperature environments. From raw material selection to processing technology, to final product inspection, there are detailed and strict specifications to ensure that the steel pipe can operate safely and reliably under harsh conditions such as high temperature and high pressure.
According to the production standards of ASME B36.10M and ASME B36.19M, seamless pipe sizes can range from 1/8”to 48”(DN6-1200), covering a wide range. There are also various specifications for wall thickness, such as SCH30, SCH40, STD (standard wall thickness), XS (thickened), SCH80, SCH160, XXS (extra thick), etc. Different wall thickness specifications are suitable for different application scenarios and pressure requirements.

The weight of a steel pipe is closely related to its outer diameter, wall thickness, and length. The calculation formula is: weight per meter (kg/m)=(outer diameter wall thickness) × wall thickness × material density coefficient, with slight differences in coefficient for different materials.
For example, for a carbon steel seamless pipe with an outer diameter of 114.3mm and a wall thickness of 6.02mm, which is calculated as (114.3-6.02) × 6.02 × 0.02466≈ 16.07kg/m.

Carbon Steel Seamless Pipe
Alloy Steel Seamless Pipe 
Stainless Steel Seamless Pipe
High strength: Materials such as carbon steel, alloy, and stainless steel endow seamless pipes with high strength. For example, ASTM A335 alloy seamless steel pipes can withstand strong tensile and compressive forces, are not prone to fracture and plastic deformation, and are suitable for engineering scenarios with high loads.
Good corrosion resistance: Seamless steel pipe made of stainless steel have excellent corrosion resistance under the action of alloy elements such as chromium and nickel. Even in harsh corrosive environments, it can maintain stability for a long time, reduce pipeline corrosion damage, and extend service life.
High temperature resistance: American standard seamless pipe have good high temperature resistance and can maintain their mechanical properties and structural stability in high temperature environments.
Oil and gas industry: widely used in oil well pipelines, oil and gas pipelines, etc. In the process of oil extraction, seamless pipes, as oil well pipes, need to withstand underground high pressure and harsh corrosive environments. Their high strength and corrosion resistance ensure the safety and stability of oil and gas transportation. In long-distance oil and gas pipelines, seamless pipes can ensure the sealing and pressure resistance of the pipeline, reducing the risk of leakage.
Chemical industry: used for transporting various chemical raw materials and products. There are many corrosive media involved in chemical production, and the corrosion resistance of stainless steel seamless pipes makes them an ideal choice for chemical pipelines.
The power industry plays an important role in boiler pipelines, condenser pipelines, and other aspects of power plants. Its high temperature resistance and high strength can meet the working environment requirements of high temperature and high voltage in power production, ensuring the safe and stable operation of power equipment.
Mechanical manufacturing industry: The high strength and good processing performance of American standard seamless pipes enable them to be machined into various precision parts, effectively extending the service life of mechanical parts and improving the overall performance of mechanical equipment.
Economical and efficient: Compared with solid steel, American standard seamless pipes are lighter in weight and belong to economical section steel when the bending and torsional strength is the same. This can not only save material costs, but also reduce costs during transportation and installation. Meanwhile, its longer service life reduces the frequency of pipeline replacement and maintenance, further improving economic benefits.
Safe and reliable: Strict production standards and high-quality materials ensure the safety and reliability of seamless pipes under various complex working conditions. Whether under high pressure, high temperature or strong corrosive environment, it can operate stably, reduce the possibility of accidents, and ensure the safety of personnel and equipment.
